In CCS, I have written my code as stated below and it shows error as "Description Resource Path Location Type #1965 cannot open source file "inc/hw_memmap.h" main.c /lab02 line 3 C/C++ Problem" and a warning also.

my code is:

#include <stdint.h>
#include <stdbool.h>
#include "inc/hw_memmap.h"
#include "inc/hw_types.h"
#include "driverlib/sysctl.h"
#include "driverlib/gpio.h"

uint8_t ui8PinData=1;

int main(void)
{
SysCtlClockFreqSet((SYSCTL_XTAL_25MHZ | SYSCTL_OSC_MAIN | SYSCTL_USE_PLL | SYSCTL_CFG_VCO_480), 120000000);

SysCtlPeripheralEnable(SYSCTL_PERIPH_GPION);
GPIOPinTypeGPIOOutput(GPIO_PORTN_BASE, GPIO_PIN_0|GPIO_PIN_1);
GPIOPinWrite(GPIO_PORTN_BASE, GPIO_PIN_0|GPIO_PIN_1, 0x00);

while(1)
{
GPIOPinWrite(GPIO_PORTN_BASE, GPIO_PIN_0 | GPIO_PIN_1, ui8PinData);
SysCtlDelay(2000000);
if(ui8PinData==4) {ui8PinData=1;} else {ui8PinData=ui8PinData*2;}
}
}

and a warning also comes as Invalid project path : include path not found.

will you please tell me how to change the included path and how to do my first program successfully.
